Patient Counseling Information
This drug may cause vision disorder, symptomatic bradycardia or fatigue, if affected, do not drive or operate machinery.
Monitoring Parameters
Monitor CBC, LFT, renal function, heart rate, BP, ECG and electrolytes; ophth evaluation. Assess pulmonary symptoms for interstitial lung disease or pneumonitis.
Drug Interactions
Plasma concentration is increased by potent CYP3A inhibitors (e.g. atazanavir, clarithromycin, indinavir, ketoconazole, saquinavir) and decreased by CYP3A inducers (e.g. carbamazepine, phenobarbital, phenytoin, rifabutin, rifampicin). Increased risk of bradycardia w/ non-dihydropyridine Ca channel blockers, β-blockers, clonidine, digoxin, anticholinesterases, pilocarpine. Increased risk of torsades de pointes w/ QTc prolonging agents (e.g. disopyramide, quinidine, amiodarone, sotalol, cisapride).
Food Interaction
Increased plasma concentration w/ grapefruit or grapefruit juice. Reduced plasma concentration w/ St John’s wort.
Mechanism of Action: Crizotinib, a tyrosine kinase inhibitor, selectively inhibits anaplastic lymphoma kinase (ALK). In patients w/ ALK-positive non-small cell lung carcinoma (NSCLC), the ALK gene is abnormally activated due to mutations or translocations, which may lead to the expression of oncogenic fusion protein which is responsible for tumour growth. Crizotinib inhibits ALK tyrosine kinase, thus reducing cellular proliferation and survival in tumours which express these fusion proteins. It also inhibits hepatocyte growth factor receptor (HGFR, c-MET), ROS1 (c-ros), and recepteur d’origine nantais (RON).
Absorption: Bioavailability: 43%. Time to peak plasma concentration: 4-6 hr.
Distribution: Plasma protein binding: 91%.
Metabolism: Metabolised in the liver via oxidation (to form crizotinib lactam), and O-dealkylation by CYP3A4/5 enzymes.
Excretion: Via faeces (63%, 53% as unchanged drug); urine (22%, 2.3% as unchanged drug). Terminal elimination half-life: 42 hr.
